The idea that IQ is heritable, as in the genes from your parents have a substantial effect on your IQ (leaving aside diseases), is far from established and most cognitive psychologists would violently disagree. Any effect from your parent's genes is drowned out by socioeconomic status, the environment, pollution, time, education, etc. For example, the correlation between your IQ and your cousin's IQ is almost negligi…
Wow. You need to read some behavioral genetics. Let me know if you care to. I'll give you references. They've found g heritable in primates other than humans as well. The amount of work we do to believe that biology is not a factor is stunning. This is what a 'cultural taboo' looks like.
I'll repeat something from my previous post because it's very important. When scientists talk about heritability they don't mean it the layman's sense of "these people have low IQ and that is conserved over time unless they go and breed with others". There's 0 evidence for this even if you look at a small and until recently fairly isolated population like that of Iceland. The correlation between your IQ and your cousin is almost non-existent even if you're part of the same cultural group in the same village. You're simply misinterpreting headlines without taking the time to understand what people mean.
There's no "cultural taboo" here. Scientists want to find the truth and we all work very diligently at it. We're just lucky that reality doesn't back up racist and sexist viewpoints and that the scientific evidence is clearly not on your side.
